TROUBLESHOOTING [GENERAL]
How
do you use a VGA extension cable?
Remove
the extension cable for the test. Is the image now in focus? If not, optimize
the image by working through the instructions in the "Adjusting the
refresh rate" section on the link "Adjusting the Screen Resolution".
It is normal for blurring to occur due to conduction losses in extension
cables. You can minimize these losses by using an extension cable with better
conduction quality or with a built-in booster.
Pixel
errors can be seen:
One
of several pixels is permanently black, one or morepixels are permanently
white, one or more pixels are permanently red, green, blue or another color.
Clean
the LCD screen.
Cycle
power on-off.
These
pixels are permanently on or off and that isa natural defect occurs in LCD technology.
The
image has a faulty coloration:
It
has a yellow, blue or pink appearance.
Select
MENU > PICTURE > Color > Reset Color, and then choose “YES” in the
“Caution” message box to reset the color settings to the factory defaults.
If
the image is still not correct and the OSD also has faulty coloration, this
means one of the three primary colors is missing in the signal input. Now check
the signal cable connectors. If any pin is bent or broken off, please contact
your dealer to get necessary support.
No
image can be seen:
Is
the prompt on the display illuminated in green?
If
the LED is illuminated in green and there is a message “Out of Range” on the
screen, this means you are using a display mode that this monitor does not
support, please change the setting to one of the supported mode. Please read
the “Preset display modes” section from the link "Adjusting the Screen
Resolution".
Faint
shadow from the static image displayed is visible on the screen:

the power management function to let your computer and monitor go into a low
power "sleep" mode when not actively in use.
Use
a screensaver to prevent the occurrence of image retention.
Is
the prompt on the display illuminated in orange?
If
the LED is illuminated in orange, the power management mode is active. Press
any button on the computer keyboard or move the mouse. If that does not help,
check the signal cable connectors. If any pin is bent or broken off, please
contact your dealer to get necessary support.
Is
the prompt on the display not illuminated at all?
Check
the power supply mains socket, the external power supply and the mains switch.
The
image is distorted, flashes or flickers:

from different input sources may appear distorted or stretched on the monitor
running at its native resolution. To have the optimal display performance of
each type of input sources, you can use the "Display
Mode"
function to set a proper aspect ratio for the input sources.
The
image is displaced in one direction:
